To be the alcohol of liquid under the room temperature such as methanol, ethyl alcohol, propyl alcohol, gloves embryo temperature is 45~55 DEG C when impregnating coagulator.
Chemical fibre knitted gloves blastopore hole is larger, and such as without the processing of pre-soaked coagulator, when can lead to impregnation, sizing material oozes
Thoroughly on the inside of gloves embryo (side contacted with skin of hand), user is uncomfortable, product is nonconforming.And the hole of cotton interlock gloves
Hole very little, generally will not there is a situation where penetrate into inside after impregnation.When impregnating coagulator, gloves embryo requires heat to a constant temperature
Degree, can so help the alcohol (alcohol of liquid under the room temperature such as methanol or ethyl alcohol) in coagulator that can quickly volatilize away, otherwise
If gloves temperature when immersing in coagulator is too low, alcohol liquid is difficult to wave to send out in time, and follow-up impregnation will appear when processing
Drop wears, seep through, or a series of problems, such as decortication, so gloves embryo will have a certain temperature when dipping coagulator, preferably 45 DEG C~
55℃。
The beneficial effects of the invention are as follows:
The present invention prepare butyronitrile wrinkle rubber cement when, select appropriate deal NBR latex and vulcanizing agent, assistant with appropriate part
Butyronitrile corrugation rubber cement is prepared after parking presulfurization in the activating agent and vulcanization accelerator of amount;Simultaneously as needed, may be used also
To add crosslinking agent during preparing butyronitrile corrugation rubber cement, it is used cooperatively with vulcanizing agent, crosslinking agent is mainly used for vulcanizing agent
Cannot act on active site (including vulcanizing agent additive amount it is less and what the sulfurate activity point and vulcanizing agent that cannot act on did not acted on
Unvulcanised active site) crosslinked action is played, further increase the oil resistivity and wearability of product.After gloves embryo impregnation, use
The surface treatment finish being made of the first finish, the second finish and third finish, is swollen the glue-line of gloves embryo surface, is broken
, there is crepe structure in film surface in breast and the solidifying processing of rush, are most prepared into the nitrile rubber corrugation through vulcanizing drying and processing afterwards

In, it is taken out after 3~5 seconds.
Step S4, vulcanization drying:By product among gloves first at 75 DEG C, cryogenic vulcanization dries 30min, finally in high temperature sulphur
Change at 110~120 DEG C of temperature, high temperature vulcanized drying 80min, butyronitrile corrugation gloves are made.
It wrinkles gloves according to the method manufacture nitrile rubber of embodiment 1-8, in oil resistant, wear-resisting, corrosion-resistant, heat-resisting aspect ratio
Existing butyronitrile gloves are more preferable, and non-skid property and existing natural emulsion corrugation gloves are close.After tested, the nitrile rubber of preparation
Gloves wrinkle up to the wear-resisting class 4 grades of EN388 (European standard).
